3.7. Connection of pure water tank and effluent tank
1) Pour the necessary quantity of pure water for washing into the pure water tank,
and close the lid.
2) Connect the pure water inlet tube to the washing pump inlet side.
3) Connect the pure water outlet tube to the washing pump outlet side, connect the
other side to the pure water joint of the washing tank, and fix them using supplied
cable ties.
4) Connect the drain tube to the washing tank effluent joint, and fix it using a supplied
cable tie. Insert the other side in the hole in the lid of the effluent tank, and attach
two supplied cable ties to prevent the tube from coming out.
*Effluent is drained to the effluent tank from the washing tank by the natural fall.
Because effluent will not be drained if the tip of the drain tube is soaked in effluent,
fix the tip of the drain tube in the position immediately below the lid of the effluent
tank, as shown in the figure.

9) Attach the pure water inlet and outlet tubes as before.
Rinse pump
Replace the rinse pump approximately three years or 3,000 hours
after the start of use.
If there is an abnormality such as an abnormal sound during
rotation, replace the rinse pump even before the above period
expires.
Replacement procedure
1) After carrying out the washing operation and draining pure
water in the flow path, disconnect the pure water inlet and outlet
tubes.
